Tyre inflation valve connectable to a transducer

Abstract

A valve for inflating tires of tired wheels associable with a transducer provided with electronic sensors for detection and transmission of certain operating parameters of the tire. The valve is arranged for being mounted on a rim of a wheel for vehicles so that the valve projects outside the rim and the transducer is positioned within a chamber delimited by the tire and by the rim. The valve includes signaling units which, once the valve has been mounted, are visible from the outside of the wheel. The signaling units are correlated univocally with the orientation of the transducer, and are arranged for indicating the position assumed by the transducer inside said chamber.

The invention claimed is: 
     
       1. A valve ( 30 ) for inflating tires ( 10 ) associable with a transducer ( 40 ) provided with electronic sensors for detection and transmission of certain operating parameters of the tire ( 10 ), wherein the valve is arranged for being mounted on a rim ( 20 ) of a wheel for vehicles so that the valve ( 30 ) projects outside the rim ( 20 ) and the transducer ( 40 ) is positioned within a chamber ( 50 ) delimited by the tire ( 10 ) and by the rim ( 20 ), said valve ( 30 ) comprising:
 means for signaling ( 70 ,  80 ) that, once the valve has been mounted, are visible from the outside of the wheel, 
 wherein said means for signaling are correlated univocally with the orientation of the transducer ( 40 ), and are arranged for indicating the position assumed by the transducer inside said chamber ( 50 ). 
 
     
     
       2. The valve ( 30 ) according to  claim 1 , wherein said means for signaling ( 70 ,  80 ) are chosen among markings, writings, incisions, relieves, colored signs, or variations of geometrical shape. 
     
     
       3. The valve ( 30 ) according to  claim 2 , wherein said means for signaling with variations of geometrical shape comprise a flat section ( 80 ) on a portion of the valve ( 30 ) that is outside the wheel rim ( 20 ). 
     
     
       4. The valve ( 30 ) according to  claim 2 , wherein said means for signaling ( 80 ) with variations of geometrical shape are associated with unique means for joining having variations of geometrical shape between said valve ( 30 ) and said transducer ( 40 ) on a portion of the valve ( 30 ) inside the wheel rim ( 20 ). 
     
     
       5. The valve ( 30 ) according to  claim 4 , wherein said unique means for joining with variations of geometrical shape comprise a flat face ( 90 ). 
     
     
       6. The valve ( 30 ) according to  claim 2 , wherein said means for signaling with variations of geometrical shape cooperate mechanically with equipment arranged for orienting an assembly of the valve ( 30 ) and the transducer ( 40 ). 
     
     
       7. A valve transducer assembly comprising the valve ( 30 ) according to  claim 1  and the transducer ( 40 ). 
     
     
       8. A tired wheel for motor vehicles comprising a valve-transducer assembly according to  claim 7 . 
     
     
       9. A tired vehicle comprising the tired wheel according to  claim 8 . 
     
     
       10. The valve ( 30 ) according to  claim 1 , wherein the indicating the position assumed by the transducer inside said chamber ( 50 ) includes indicating a rotational position of the transducer with respect to the valve.
